The Discovery Space in St Patrick's Cathedral helps users discover the history of the church, including its monuments, characters and stained-glass windows.

Built in 1220, the cathedral is visited by more than 450,000 people a year.

A €250,000 investment to modernise facilities includes a 55-inch touch screen table, allowing visitors to take a tour and explore hidden areas including the rooftop. An app has also been developed.

"This fantastic new resource will make the cathedral even more accessible to those interested in our rich cultural heritage, encouraging them to stay longer and allowing them to learn in a more modern and interesting way," Canon Horace McKinley said.

The project followed research suggesting there was a lack of information about the history of St Patrick's Cathedral. The centre is free for primary and secondary pupils.
